This guy not only kissed a 12 year-old girl's feet while she was sitting on a bench reading, he asked to KISS HER LIVER!!! Another woman, who was napping in a park, woke up to this same pervy guy licking her toes. The article states that "The man told her she had beautiful feet, then put all five of her toes into his mouth."
I can't really imagine a compulsion that is so strong it drives you to lick feet. Especially a stranger's feet. All I can think of is my mom's voice saying "you have NO idea where those feet have been."
